Dal Soup
The simplest Indian soup — masoor dal cooked with minimal spices, blended smooth. No cream, no stock. The lemon and cumin finish is everything.

Dal soup is the healthy Indian restaurant staple — thin, light, protein-rich, with a clean flavour that makes it a good starter or light meal. The key is masoor dal: it cooks fast, blends completely smooth, and needs almost nothing else to taste good. The common mistake is adding cream or butter to make it richer — the correct approach is proper bhuno of the onion-tomato base that develops natural sweetness and depth without any fat beyond the tadka.
Combine all ingredients (except tadka and lemon) in a pot. Bring to boil and simmer 20 minutes until lentils are completely soft and disintegrating.
Masoor dal (red lentils) is the fastest-cooking dal — it has no seed coat and its starch gelatinises within 15–20 minutes at a simmer. The absence of the tough seed coat means no soaking is needed. Cooking lentils and aromatics together from the start allows the onion and tomato flavour compounds to penetrate the lentil cells as they cook.
Blend the cooked mixture until completely smooth. Add hot water to achieve a thin soup consistency — thinner than regular dal. Return to heat, adjust seasoning.
Masoor dal blends to a completely smooth texture because its starch fully gelatinises and the absence of seed coat means no fibrous particles remain. The smooth texture and thin consistency are what distinguish dal soup from dal — the soup should flow easily, not coat a spoon.
Make a tadka with ghee, cumin seeds, hing and dried red chilli. Pour over the soup. Add generous lemon juice at serving.
The cumin tadka adds fat-soluble aromatic compounds (cuminaldehyde) to the water-based soup — without it the soup tastes one-dimensional. Lemon juice is essential — citric acid brightens the earthiness of lentils and stimulates appetite. The interaction between glutamate (from lentils) and citric acid (from lemon) enhances perceived flavour intensity.
